Bull float is tool that is used to level concrete after it has initially been poured. It is put together in sections. On the lower end, there is a rectangular piece attached. These pieces come in different sizes and shapes. After the concrete is poured and screed, the bull float can be used to level out any humps or fill in any dips. As the float goes across the concrete, the rock is pushed down which leaves only the concrete cream on top. After the concrete has set up a little, the slab can be bull floated again and slicks the surface out even more. When the bull float is pushed, the handle is held low so the back edge floats across the concrete. As the bull float is pulled back, the handle is held high and the front edge floats the surface. Each push and pull stops approximately one foot short of the form so as not to push concrete over the form. This allows the edges to be hand troweled with a finishing trowel
